Short answer
Magnesium glycinate is one of the most practical forms of magnesium for sleep because it supports relaxation without acting like a sedative.
For many people, 100 to 300 mg of elemental magnesium taken 30 to 90 minutes before bed is a sensible range.
Magnesium is one of the most common sleep supplements for a reason. It supports relaxation, helps the nervous system downshift at night, and may reduce the tense, wired feeling that keeps sleep latency high.
Why magnesium can help sleep
- Physical relaxation and reduced muscle tension
- Stress modulation and a calmer evening state
- A smoother transition from alertness into sleep readiness
Magnesium does not force sleep like a knockout pill. It helps make the nervous system more sleep ready.
